Texas Instruments DAC38RF97
The DAC38RF86/96 is a family of high-performance, dual-channel, 14-bit, 9-GSPS, RF-sampling digital-toanalog converters (DACs) that are capable of synthesizing wideband signals from 0 to 4.5 GHz. The DAC38RF87/97 is also a family of highperformance, dual-channel, 14-bit, 6-GSPS, RFsampling digital-to-analog converters (DACs) that are capable of synthesizing wideband signals from 0 to 3 GHz. The devices feature a low-power JESD204B Interface with up to 8 lanes with a maximum bit rate of 12.5 Gbps allowing an input data rate of 1.25 GSPS complex per channel.FEATURES
